Answer 2

Answer:

Explanation:

1) A device used to measure electric current in a circuit is called______

Ans-Ammeter

mmeterAn instrument called ammeter measures electric current in a circuit. It is always connected in series in a circuit through which the current is to be measured.

2) ln static electricity that charges are at/in _______

Ans- Negative to Positive.

The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).

3) A microphone convert ______ energy into ______energy

Ans-Sound energy into Electrical energy.

The Energy change that takes place in a Microphone is Sound energy to Electrical energy. A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil.

4)The rate of flow of charges through a conductor is called ______

Ans-Electric current

The rate of flow of electric charge is known as electric current. Electric current is expressed by the rate of flow of electric charges.

5) A ______ cell can be used only once, until it discharges.

Ans-Primary

A primary cell is one that cannot easily be recharged after one use, and are discarded following discharge.

6) A/an _____ is a solution or semi solid paste that allows the passage of electric current.

Ans-The passage of an electric current through a solution causes chemical effects.

Ans-The passage of an electric current through a solution causes chemical effects.When an electric current passes through a solution, the solution decomposes into its positive and negative ions. This process of decomposition of the solution is a chemical effect.

7) _____ cell produces electricity from sunlight.

Ans-Photovoltaic cells

Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity.

Here are your answer...

However,I am not sure about the 6th no. answer but I tried my best...

Hope it's helpful...
